Abstract: PURPOSE:To simplify the positioning and detachment of an external electrode and to elastically press said electrode to a living body by providing the external electrode to the other end of a support arm body and providing a contraction body, whose axial length is extended and contracted by dropping or raising pressure, to the support arm body. CONSTITUTION:An external electrode 19 is mounted to the shaft part 15 becoming the leading end of a support arm body 18 and a balloon 20 is provided to the surface on the side applied to the surface of a living body of the external electrode 19. When the tubular rubber artificial muscles 21a, 21b provided to an arm member 11 so as to form a pair and the tubular rubber artificial muscles 21c, 21d provided to an arm member 16 so as to form a pair are together internally pressurized by air, said muscles generate force in the direction contracting in the axial direction and, when said muscles are evacuated, the force is returned to the origin. Therefore, when contract bodies 21a-21d are operated so as to be pressurized and evacuated, the arm members 11, 16 of the support arm body 18 are revolved so as to generate movement rich in elasticity. By this movement, the external electrode 19 is simply set to the surface of a living body at a predetermined position or detached therefrom and, at the same time, the whole of the external electrode 19 can be elastically pressed to the surface of the living body.

Title: Conveyor for laser cutter
Inventor: MATSUOKA HIROSHI
IPC: B23K26/38
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a conveyor for a laser cutter which reduces a cloth cutting error caused by the reflection of laser light and to improve the yield of cloth by preventing the residue of cloth cut by the laser light from adhering to the cloth again. SOLUTION: A plurality of conveyor bodies 35 are connected to form an endless conveyor belt 31. Cloth is held by the conveyor bodies 35 by absorption and is irradiated with laser beam from a laser head to cut the cloth in a desired shape. Each conveyor body 35 is constituted by arranging a plurality of plates, which extend in the direction of travel of the conveyor belt 31, parallel to each other in the direction perpendicular to the direction of travel. The plates hold the cloth on the surface in the direction of thickness thereof. The conveyor body 35 is shaped like a hurdle or a longitudinal grid. Compared with a conventional honeycomb structure, the surface area of a holding body irradiated with the laser beam is reduced and hence a cutting error caused by the reflection of the laser beam (defective ratio) is reduced.  Since the holding body has slits or longitudinal grooves extending in the direction of travel of the conveyor belt 31, the adhering residue of cloth can be completely removed by a brush.
